4y - y + 7y
4y - y = 3y
3y + 7y = 10y
10y is your answer
hope this helps
Answer:
I can't see the question
Step-by-step explanation:
Answer:
y = x + 3
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
1x is the same as x
When we add or subtract polynomials, the addition or subtraction is applied to the coefficients of the terms of equal powers.
For the given polynomials, we are required to do subtraction as follows:
(-4.1 x^2 + 0.9 x - 9.8) - (1.7 x^2 - 2.4 x - 1.6)
= -4.1 x^2 + 0.9 x - 9.8 - 1.7 x^2 + 2.4 x + 1.6
= (-4.1-1.7) x^2 + (0.9+2.4) x + (-9.8+1.6)
= -5.8 x^2 + 3.3 x - 8.2
The final expression (solution) is:
-5.8 x^2 + 3.3 x - 8.2
